IAQ (indoor air quality) at a glance! Particle sensor to detect air-bourne particles in a room. It is sensitive to dust, particles and cigarette smoke which can trigger many allergic symptoms.
PPD 42NJ (Particle Sensor Unit)
Based on the light scattering method, it always detects airborne particles. Pulse output that corresponds to concentration per unit volume of particles can be obtained, with using an original detection method based on light scattered principle similar to the particle counter.
PPD 20V (Particle Sensor Unit)
Based on the light scattering method, it always detects the An analog voltage that corresponds to concentration per unit volume of particles can be obtained, with using an original detection method based on light scattered principle similar to the particle counter.
PPD 60PV (Particle Sensor Unit)
Based on the light scattering method, same as particle counters, it detects air borne particles from cleanliness class 100,000 ～ 1,000,000.
Our Particle Sensors, PPD42NJ and PPD20V can detect dust in your house and automatically control air-purifiers and air-quality monitors by installing the sensor in your products. And a newly developed PPD60PV can detect particles cleanliness class 100,000 ～ 1,000,000, it can be installed in Fan Filter Units and Clean Systems to control cleanliness of operation line. By consulting your expected usage, we can recommend a particle sensor that best suits your needs.
Application : Air Purifier, Air Quality Monitor.
* Heater (resistor) generating updraft. Infrared light beam from LED has been focused with Lens to sensing point at the center.
* Airborne particles have been taken into the sensor box with the updraft.
* Particle passing through sensing point scatters light, and receptor receive scattered light through the lens and transformed into pulse signal. Pulse per unit time is proportional to the particle concentration. Pulse signal are to be converted into voltage output. (PPD20V)
